Original GitHub issue: https://github.com/Seldaek/monolog/issues/800

Within my code, I'm trying to get multiple files, each that only has log messages of a particular significance, so that when it comes time to check for logs I know that each file will only have a particular class of errors.

Is there a way to set that up? So that "Notice" errors go into a Notice log file, Critical into a critical file?

Ideally, I'd like to be able to do something like:

$message->addNotice("$foo has been deleted.");

and then later...

$message->addCritical("$bar is missing.");

so that I'm using $message for everything, but the errors are going their separate ways.

Or do I need:

$messageNotice->addNotice("something");

$messageCritical->addCritical("something else");

and have different loggers for each type of error?

You could use the FilterHandler to do that, basically creating 8 StreamHandlers with diff file names, and 8 FilterHandler wrapping them, each listening to one single level like e.g. array(Logger::ERROR).

Typically though I think it's better to filter the logs whenever you read them than when writing them, because otherwise reading a full request's logs becomes really hard if you have to combine 8 different files. Up to you though.
